VERTICAL GAS'ENGIN'E.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed February 1, 19GB. Serial No. 299,008.

To all whom it may concern:

Be it known that I, WILHELM von (EcnEL- nAEUsER, a subject of the King of Prussia, residing-et Dessau, Anhalt, Germanv, have invented Improvements in Vertical Gos-Engines, of which the following is e specifiestion.

This invention relates to the improvements two-oficio gas-engines of the construction shown in my prior patents, 508,833` dated November` 14, 1893, and 596,613, dated Jennery 4, 1898, but more especially to the vertical type of some.

This invention is not merelyr an improvement upon known inventions und construetions in the line of bining such improvements with newly-invented features overcomes the recognized dil'liculties of the vertical type of gos-engines and at the some time increases the ellirrieney of the engine, as will be more lullv hereinafter ex lx1-ined.

Vn the im rovcd engine two pistons move in opposite directions in o single working eji'linder in sue-h e way that toward the end of the expansion stroke the exhoust-ports und the inlet-.pruts for the gos and air are controlled by the pistons. First the one piston exhaust-ports to allow the escupe of the grises ol' combustion into the utmoshere." Then the other piston o )ons the oirinlet p orts to nllow the entry olt fresh nir to displneethe gases of combustion in the ilinder and then opens the inlet-ports for the gus.

The enteringr gils now forms with the entering air the proper explosive mixture. On the return stroke of the pistons the ports nre closed in the reverse manner, the mixture compressed, and nt `the proper point ol the piston-Stroke the charge 1s ignited. The working eyele thus completed is then reposted.

The foregoing-described method of operotion shows that the successive exhaust of the Uruses of combustion, the displacement b v resh oir, und the following mixing of gos ond nirtukc place while the e \linder-spnce between the, pistons is in communication with the atmosphere. ln order to avoid :my loss of gus, the displacement of the various ,enses must tolw platee in n most uniform lminner and is properl)r accomplished bjr the wellnown nrrengement ofthe ports in slot lorm around the entire circumference of the cylinges-engines, but by eoml l i l l i i l l l l i l i i l i l t i der. However, the feet that the gas and air sup ly pipes, es well as the exhaust-pipe, in all nown constructions of similar gas-engines in eoeh crise ore connected to corre spending chambers around the ports et one side only makes it evident that the displacement of the various gases cannot take nlece in such a, uniform manner as is desireb efor the perfect o eration of the engine. Besides, the unavoida ly long ehnfnnels for ges und eir peculiar to their construction form receptacles which not only retard the movement of the gets into the working ports, but also cause :t one-sided entrance und exit of the gases, which prevents that uniform displacement of the grises so neeesserr for the proper operation of this t) ie of engineh Furthermore, the time lost y such retarded movement of the grises necessarily reduces the efficiency of the engine.

Referring especially to gas-engines of the vertical tj e, it is a well-known friet that the eli'ee-ts of tiie explosion, movement oimztsses, reaction of the exhausting grises eseoping suddenlyV sind under still e eompurfltivehr high pressure nre dillieult to overcome. The ell'eet o' the explosion und of the movement of messes in working ports nre overcome by the :arrangement ol the pistons working in an opposite direction, which bnlonees the force due to the movements of the mns-ses find to the explosion. l lhe unfavorable ell'ect ot' the exhaust-gases due to the one-sided arrangement of the exluiust-pipe, however, is not overcome in ung; of the known constructions of ,ens-engines lt is the object of this invention to aecomplish the following results: quick and uniform reinoviil of t hentingof the bridges between the exhaust outlet-ports in theeylinder-wnll, balancing the renelion of the exhaust-gases escaping suddenly and still under high nessme,uniforni cooling of the working eyhnder find the exluulst-elnunber, ond the s vnnuetrieol arrangement of the exhaust-chamber forming almost fevornble'nmnner ol' supporting, strengthening, und still'ening the vorioitsports of the enitine, thereby avoiding ell special su ports, izmmes, &e. The means to eeeomplislliJ these objects, rangement oud proporlioning of t 1e various ports, und the 'res-idling,r improvements in the general arrangement of the engine, os well as he enses ol combustion, uniform loo in the internal working conditions, are embraced in my invention, as more fully specified hereafter.

In the accompanying drawings, Figure l1 represents a vertical section through the Working cylinder. Fig. 2 represents a similar section at right angles to Fig. ,l through the working cylinder with a charging-pump. Fig. 3 represents a horizontal section throrgh io the frame on line 3 3, Fig. 2. Fig. 4 represents a horizontal section through the cxha-'st-port on line 4 4, Fig. l. Fig. represents ahorizontal section through the gas-inlet port on line 5 5, Fig. l. 1"ig. 6 re resents a horizontal i 5 section through air-in et ort on line 6 6, Fig. 1. Fig. 7 represents a iorizontal section, and Fig. 52 represents a vertical section, thro .gh .trt of an engine-frame in modification. zo In the working cylinder a, which is open at both ends, two pistons c and c move in o posite directions and toward .the 4end of t e outward and expansion stroke control the outlet and inlet openings in the following z 5 order: First, the piston cZ opens' the outletports s for the escape of the gases of Cornhus- `tion intothe atmosphere. At the momen't the exlia istgascs drop to atmospheric pressure the iston c opens the air-inlet ports s 3o to admit Fresh air for removing gases oi' com-r bustion and inallxY opens the as-inlet ports s to admit the fuel-gas, whic with thc air entering through the ports s', forms the eX- plosive"mixture. On the return stroke the ports are closed in thc reverse order, the inclosed mixture compressed, and at the end of the 'stroke ignited in the ustal manner. A special and important feature of this construction is the immediate connection of the 4o discharge-pipes dd of the charging-pump to the corresponding inlet-pipes d2 d of the rcceiving-chambersf ft.

The working cylinder a is constructed referably, in two parts, joined and iitted Into the casings as' and at in the manner indicated, so as to allow for independent movem nt of the different parts on account of exiiansion and contraction. T 1e casings, besides forming the cooling-cham )ers around 5o the cylinder, also contain tzhe receiving-chambers'f for air and P for gas, as viilell as the exhaust-chamber f. The receivi lg-chamhers are arranged around the inlet-ports and provided with means for thc imnieqate connec- 5 5 tion of the discharge-pipes of t e charging- Aipes thereto, as above mentioned. The immediate connectio'n of' the dischargespaces of the charginpumps with the receiving-chambers thus o tained is of great imo pertence, as the pumps dischar fe witit ever)v stroke gas and air direct into t ic espective receivinv-chambcrs, there to be st. red until4 admitted into the workin cylinder through the rings of ports provide in the entire circumference of the cylinder-wall, ushvret ofore cx lained.

n the operation of n` two-circle ges-engine it is characteristic that rlufrging-pumps press the gas and nir into thtir respective reeciving-chanihtrs, and from the lutter thtl lcompressed gus und air alter the opening' of the ports hy the pistou enters theuorhing spare of the Cylinder. The amo: nt of gus and oir entering the \liudrr, ns nulles the proper proportion of the luixt: re, depends, first, upon th(` size of its inlet-openings; sccond, i pon thc size of the rm ri\ ing-Chanda r, and, third, rpon the qi antit \Y of the gas and air delivered into the rer'riving-rhandit-rs hy the pumps. The rcsstrc ol' the gas und air thus treated in tioir respective retcivingchambers depends upon the receiving caparity of same. It is now ohvioi s that u ith a change of the receiving rapatity of the chambers the pressure of either gas or air can be varied, and the amount of gas and air entering the cylinder can be regulated so as to obtain theproper and desired proportion of the mixture. The possibility ofsl ch regi.'- lation is of great importance for all gas-ongines where there is a possihility or necessity for r'sing gases of diilercnt qi ulity and n ith different pro )ortions in the ntixti re. 'Ille advantage ci this regulation becomes still more pronotnccd from the fart that thc rnginc may he hrilt according to one standard construction, and `vet nitl'ioct any change in the construction can be accommodated to an).T condition of thc operation and quantity of gas Lsed.

vThe arrangement oi the receiving-chambers around the working cylinder allows the same to he utilized as a hase for the entire upper part ol the engine, as is indicated in the drawings, and at the same tinic ns a convenient and suitable connection hctween this upper part and the base-frame ol the engine hy means e" the two stand ards or columns n and n. The columns fn and n2 are constructed hollow, and the hollow space of the column n is connected direct to the receivingchamherf2 hy means of the connecting-piece 'i'. The hollow space of column n is connected to receiving-chemherf by means of connecting-piece 'i'. The connecting-piece 'i' occupies part of the receiving-chamberf2 and separated from the same b the wall k Fig. 5. Thel hollow spaces in coliimns n and n* are thus utilized as` extensions ot the recciving-chambers'if. nd f.
